Both are good bands, but metallica's a much more a sellout of a band than Motorhead. Metallica went gay since the black album to just try to gain radio friendly style to get more money. Motorhead stayed more true to their music and fans. Sorry metallica fans.
Motorhead easily Metallica made some awesome songs back in the day but they sold out pretty fast after the Black Album it went all downhill. Also Lars whining about Napster will forever be stuck in my head. lol
I love Motorhead, but Metallica took what they were doing and made it better, more popular, and evolved over the years. I don't like what Metallica has become, frankly I haven't listened to them in years, but they are still one of my favorite bands and even their "sellout" albums (Black, Load, Reload) were far more enjoyable than the other crap that we had to listen to during the 90's.
And no matter what you think of their music from a preference point, they are incredibly talented musicians. Kirk Hammett is one of the greatest guitarists ever. The fusion of San Francisco Orchestra and Metallica, while note entirely original, was arguably one of the greatest musical moments in recent memory.
Metallica for the 1st three albums and garage days. They lost me after that but those albums easily win the debate in my opinion.
I wouldn't call Metallica sell outs. They just got older. Tastes change as you get older. Back in the 80's when I was a teen, it was all about metal for me and nothing else. These days I still listen to metal but I also listen Classic rock, punk, some rap and even some Dean Martin will play on my list at times. People change as they get older.
